TI工程师:
我在查阅BQ24040 datasheet时,发现了有关TTDM模式的以下描述:
(1)The TS terminal has two additional features, when the TS terminal is pulled low or floated/driven high. A low disables charge (similar to a high on the BAT_EN feature) and a high puts the charger in TTDM.
(2)If NTC sensing is not needed, connect this terminal to VSS through an external 10 kΩ resistor. A 250kΩ from TS to ground will prevent IC entering TTDM mode when battery with thermistor is removed.
如上所述,我使用TS脚10K下拉到地,是否是进入了TTDM模式呢?
多谢指点。
